Algebra 1 Quadratic Formulas & Applications

In this lesson we are going to take a look at some quadratic formulas and some applications of quadratics. Specifically, we will look at how you can recognize some quadratic equations or some formulas that have quadratics in them. Some situations that tend to be very common with quadratic equations, are the Pythagorean Theorem and the distance formula. You'll see how some word problems lead to quadratic equations. These usually include problems with distance, right triangles, or area. Remember we can use the principle of square roots to help isolate the squared variable.

Some word problems lead to quadratic equations. These usually include problems with distance, right triangles, or area.

The Pythagorean Theorem says a2 + b2 = c2, where a and b are the legs of the right triangle and c is the longest side.
